LAN Settings 53 Encryption When setting up wireless networks, it is important to remember that with encryption disabled, anyone with a Wireless PC can eavesdrop on your network. 3Com recommends that you get the network working with encryption disabled first and then enable it as the last step. This will simplify setting up your network. You can configure wireless security such as WEP or WPA encryption on this screen. Note: it is recommended that you use WPA encryption over WEP if your wireless clients support WPA All of the wireless clients must use the same security settings in order to connecdt to the router. ■ WPA - Wi-Fi Protected Access (WPA) is a 256 bit encryption method with keys that change over time. ■ WEP - Wireless Equivalent Privacy (WEP) is a 64 bit or 128 bit encryption method with user configurable fixed keys. WPA provides a higher level of security, provided by its longer key and dynamic changes made to the key over time. 3Com recommends that you use WPA with any clients which support it. If you enable encryption on the Router, you must reconfigure your wireless PCs to use exactly the same Encryption Type and Keys otherwise the devices will not understand each other. The encryption methods used by the Router secure data transmitted through wireless communications between the Router and its wireless clients. Enabling encryption has no security effect on data transmitted through wired (Ethernet) connections or through your connections to the Internet.
